QIBR XSU Series Crossed Cylindrical Roller Bearings: Material Options and Application Selection Guide
The QIBR XSU Series Crossed Cylindrical Roller Bearings feature an integrated inner and outer ring design with mounting holes, eliminating the need for flanges and support bases, making installation simpler. These bearings are suitable for both outer ring and inner ring rotation. They are equipped with seals that prevent contaminants from entering the bearing, reduce grease leakage, and lower maintenance costs. Both axial and radial sides feature lubrication holes for convenient multi-directional oil injection.
The QIBR XSU Series Crossed Cylindrical Roller Bearings are typically made from AISI 52100 material, which provides excellent wear resistance and strength, making them ideal for high-load applications.
For harsh environments, the XSU Series is available in AISI 440C stainless steel.
The choice of material depends on specific application requirements, such as load, strength, and environmental conditions, to ensure optimal bearing performance and service life. By considering these factors, users can select the most suitable bearings for their applications.
